Who's this Korean hottie?

I’ve seen him in some kdrama before but can’t recall which one. I don’t even know his name. Help please?


Kim Jaejoong sings and acts. Just went in the military so he will out of commission until 2017. He’s someone to watch and has a beautiful voice. First heard him sing in Triangle.


Thanks! Now I know where I saw him. He was in Protect the Boss.

Lmao XDD
Is it wrong if when I saw “hottie” in title, I immediately think to Jaejoong?

No. Just a given.
